# Claude Multi-File Coherence Checker MCP for AI Agents AI Agent Connect

> Claude Multi-File Coherence Checker MCP prevents broken code when your AI agent makes changes across multiple files. It audits imports, function signatures, and type definitions to ensure that a change in one file doesn't silently break a consumer in another. It's a deterministic way to catch the 'partial update' problem where an AI modifies a definition but forgets to update the rest of the codebase.

## Description

When you're working with an AI agent on a large codebase, the biggest risk isn't a syntax error; it's a logic gap. You ask the agent to rename a function or change a data structure, and it does exactly what you asked in the target file. But it misses the three other files that rely on that specific function or type. Suddenly, your project is riddled with broken imports and type mismatches that aren't obvious until you try to run the build. This MCP acts as a safety net for those exact moments. It provides a way to verify that changes to exports, function signatures, and types actually propagate through your entire project. Instead of manually hunting for every place a renamed function is called, you can have your agent run a check to find every broken link. It's about maintaining structural integrity during complex refactors. By connecting this to your workflow through Vinkius, you're adding a layer of deterministic validation that keeps your codebase healthy even when your agent is performing heavy-duty, multi-file modifications.

## Tools

### audit_type_propagation
Checks if changes to types or interfaces broke downstream consumers. It prevents type errors in files that rely on updated definitions.

### check_signature_consistency
Detects if modified function or class signatures still match their call sites. It finds where an updated parameter list causes a mismatch.

### validate_import_coherence
Validates that imports in the project correctly reference existing exports. It catches broken file references immediately.

## Prompt Examples

**Prompt:** 
```
I just renamed the `fetchUserData` function in `api.ts`. Did I break any imports elsewhere?
```

**Response:** 
```
I've checked the project imports. 

**Broken Imports Found:**
* `src/components/UserProfile.tsx`: Line 14 (expects `fetchUserData`)
* `src/hooks/useAuth.ts`: Line 22 (expects `fetchUserData`)

I can update these files for you now.
```

**Prompt:** 
```
I added a `timeout` parameter to the `connectDatabase` function. Are there any places where the call is now incorrect?
```

**Response:** 
```
I scanned the call sites for `connectDatabase`. 

**Signature Mismatches:**
| File | Line | Issue |
| :--- | :--- | :--- |
| `src/db/client.ts` | 45 | Missing `timeout` argument |
| `src/server/index.ts` | 112 | Missing `timeout` argument |

Would you like me to fix these calls?
```

**Prompt:** 
```
I changed the `Order` interface to make `id` a string instead of a number. Is the rest of the code still type-safe?
```

**Response:** 
```
I've audited the type propagation. There is one mismatch:

* **File:** `src/services/orderService.ts` (Line 89)
* **Error:** Property `id` is being treated as a `number` but is now a `string`.

All other consumers appear to be correctly updated.
```

## Capabilities

### Catch broken imports
Finds every instance where a file is trying to import something that no longer exists or has moved.

### Verify function call sites
Checks that modified function or class signatures still match every place they are actually called.

### Validate type integrity
Ensures that changes to interfaces or types haven't broken downstream consumers in other files.

### Audit codebase consistency
Scans the project to ensure structural changes are applied uniformly across all related files.

## Use Cases

### Renaming a core utility function
You rename a function in a shared utility file. Instead of manually searching the whole project, your agent uses validate_import_coherence to find every file that still uses the old name.

### Updating a shared TypeScript interface
You add a required field to a User interface. Your agent uses audit_type_propagation to identify every component that now has a type mismatch because of that change.

### Changing a function signature
You add a new parameter to a service method. Your agent uses check_signature_consistency to locate every call site that needs to be updated to match the new signature.

### Moving files in a large directory structure
You reorganize your project folders. Your agent uses validate_import_coherence to ensure all relative paths and imports are still pointing to the right places.

## Benefits

- Stop broken builds by using audit_type_propagation to catch type mismatches before they hit your CI/CD pipeline.
- Fix broken imports instantly with validate_import_coherence when your agent renames or moves files.
- Ensure function calls stay valid using check_signature_consistency after changing parameter lists.
- Reduce the manual effort of hunting for side effects caused by large-scale code modifications.
- Gain confidence in AI-driven refactoring by adding a deterministic validation layer to your agent's workflow.

## How It Works

The bottom line is you get a deterministic way to ensure your AI's multi-file edits don't leave a trail of broken references behind.

1. Connect the MCP to your AI client via the Vinkius dashboard.
2. Ask your agent to perform a refactor or a multi-file change.
3. Instruct the agent to run a coherence check to verify the changes across the project.

## Frequently Asked Questions

**How does the Claude Multi-File Coherence Checker prevent broken code?**
It acts as a validation layer that checks if changes to one file have broken the imports, function calls, or type definitions in other files. It catches the errors that happen when an AI agent updates a definition but misses its consumers.

**Can I use this Claude Multi-File Coherence Checker for TypeScript projects?**
Yes, it is specifically designed to handle the complexities of TypeScript, including type propagation and interface consistency across multiple files.

**Will this MCP replace my existing linter?**
No. While linters catch syntax and style issues, this MCP focuses on the structural relationship between different files, catching errors that occur during multi-file refactors that a standard linter might miss.

**How do I use the Claude Multi-File Coherence Checker with Cursor?**
You connect the MCP through Vinkius. Once connected, your agent in Cursor will have access to the validation tools to check your code's integrity automatically.

**Does this work for large-scale refactoring?**
Yes, that is its primary purpose. It helps ensure that when you perform massive changes across a large codebase, the structural links between files remain intact.

**What problem does this tool solve?**
It solves the problem of partial updates, where an AI agent modifies a function or type in one file but misses the corresponding updates in other files that use them.

**How does it detect broken imports?**
By using `validate_import_coherence`, the tool maps exported symbols in changed files and scans the project for import statements that no longer point to valid exports.

**Can it check if function arguments are still correct?**
Yes, the `check_signature_consistency` tool specifically checks if modified function or class signatures still match their call sites, including parameter counts and types.
